I can see the merit in this. I'm also not sure how it can be done as a one-click solution.

Now, you can take two actions: back up your preferences, and reinstall an earlier build .EXE that you kept. The beta testers already do this when a new test build renders sometime unworkable that is critical. As far as VSTs or other add-ons, I would think that regular registry backups and restorations are required, which a one-click solution in only BIAB cannot accomplish, I think.
